Heat treatment of pipe
Heat treatment, also called thermal treatment, is a method that put materials into troubles performing medium for heating, heat preservation and cooling. Also, it is a kind of technical process to control the performance of materials through changing the structure of fabric surface and interior organize.
Heat treatment of pipe depends on the way it is manufactured.
In the case of hot finished Pipe, no heat treatment is required. As during the manufacturing, Pipe Temp. remain in the range of heat treatment temperature till the final size and thickness are achieved.
Whereas in the case of Cold Finished Pipe, Heat treatment is required as per applicable ASTM standard. As the pipe is either cold drawn or temperature is not in maintained in the hot finish range.
Selection of heat treatment methods will depend on types of material and on what material properties you want to restore or further enhancement on existing properties.
These heat treatment methods are Normalizing, Quenching, Tempering, Solution Annealing, Stress relieving, or it is a Combination of these.
Heat treatment is a really important technological process in mechanical manufacturing. In comparison to other processing techniques, it generally doesn’t change the form of work piece is actually integrated chemical compound. It can improve the performance by changing the internal microstructure of workpieces or changing the chemical component of the workpiece surface.
Thermal treatment can reduce the inner quality perform pieces that can not found by naked eyes.
Heat treatment technology one more inevitable in helping the mechanical property, physical property and chemical property of work pieces.
Steel is the most well liked material in mechanical industry. It owns complex micro structure and can be controlled by thermal treatment. Besides, aluminum, copper, magnesium, titanium and their alloys can also get new mechanical property, physical property, chemical property and using performance due to heat treatment.
